Point taken, and agreed with, but F1 is a traditionally pretty bad example for this. They regularly, including during the Schumacher days, changed rules to try and make things closer.

I would argue F1 is as much about engineering as the driver. Hamilton on a different team likely excells, but probably doesn't win nearly as much.
Then why is all the prize money distributed based on the Constructors' championship, which is effectively which team does the best engineering? Indycar is the racing competition; F1 is car design competition that is judged by the racing ability of the cars, drivers and teams combined.
